What are the ethical issues in question form regarding the legalization of marijuana?

As requested, here are ethical issues, in question form, regarding the legalization of marijuana:

Is it the business of government to regulate the private lives of its citizens?

Can an action that has no victim (other than possibly oneself) be considered a crime?

What happened to the American ideal of life, liberty, and the pursuit of happiness? If marijuana makes people happy, do they not have the right to pursue that happiness?

Would legalization of marijuana actually cause more people to smoke it?

Does the harm done by enriching criminal organizations through the creation of a black market in marijuana outweigh the harm that marijuana smokers do to themselves by indulging in recreational drug use?

Given that marijuana has known, important medical uses, such as the alleviation of nausea, and the treatment of glaucoma, can we justify banning it just because some people use it recreationally?

Is it better to legalize marijuana to create a new taxable sector of the economy, in order to rescue bankrupt governments such as the state government of California, than it is to maintain our moral opposition to recreational drug use?

Is it not hypocritical of us to be so opposed to the recreational use of marijuana when we at the same time allow and even glorify the recreational use of alcohol? And we also allow (but no longer glorify) the recreational use of tobacco, a drug that is unquestionalby more lethal than marijuana. How can we justify such moral inconsistency?

What really is the moral difference between using marijuana to make you happy and using a legal anti-depressant or other prescribed medication to do the same thing?
